HEADER rrrncnnnrsiu.

Application filed my 1, 1921. Serial No. 481,849.

T 0 all whom it may concern:

Be it known that I, RICHARD Lnsrnn Wrnoox, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Header Mechanisms, of which the follow ing is a specification, reference being had therein to the accompanying drawings.

This invention relates to header mechanisms and refers more particularly to new and improved means for connecting and in part operating the punch slide or similar parts of a header or upsetting machine,

It is the object of this invention, among other things, to so associate the slide of a header or upsetting machine, with the means that give it relative movement upon the gate, that it' is entirely unnecessary to re gard the heretofore essential requirement of an exact angular relation of the parts, thus permitting all of the parts to operate efiiciently without accurate machining and whereby the assembly of the parts is materially facilitated and the possibility of wear and breakage reduced to the absolute minimum.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings in connection with the description hereinafter contained and wherein a preferred embodiment of the invention is disclosed for thepurpose of imparting afull understandingshifter plate 22 have been permanently se- 1 cured together so that it is absolutely essenof the same.

In the drawings,- I

Figure 1 is a side elevation of my im proved mechanism, with so much of the adjacent parts of a header or upsetting machine of a well known type, as is essential to show its connection therewith;

Figure 2 is a front view thereof with some of the adjacent parts in section;

Figure 3 is a fragmentary elevation of a portion of an alternative form, wherein a single gib is used; and j Figure 4 is another elevation of the same mechanism. 7

In the drawings, wherein like reference characters refer to corresponding parts, 10 designates a portion of the body of a header, 11 the gate that has a reciprocatory IIliOV6- ment therein beneath the caps'12, 13 a rock shaft j ournaled in the bearing 1 1 connected with the body 10 and having a plate 15 upon one end thereof with which is adjustably secured a connecting device 16 through which motion is imparted to said rock shaft.

Forming'part of the rock shaft 13 between the journal bearings 14 are the offset arms 17, joined by the tie bar 30, within which is journaled the cradle 18.

' All of the parts above described are common and well known in the header art and require no further description herein.

The punch slide 19, to which is adjustably secured the punch block 20 having the punches 21 fixed therein, is movably mounted in the front end of the gate 11. Slidably mounted in the cradle 18 is a shifter plate 22 held therein with proper frictional engagement by gibs' 23 against which abut thenadjusting screws 24:.

A hinged connection'is made between the punch slide 19 andshifter plate 22 by the pin 25 that passes through lugs 26 on the shifter plate 22 and. the lug 27 on the end of the punch slide 19. For convenience cotter pins 28 project through the outer ends of the pin 25 to prevent displacement thereof, but other well known means may be adopted for this purpose if desired. While the pivotal connection shown and described is the preferred form thereof, it

is possible, however, to substitute other forms of such connection within my invention.

Heretofore, the punch slide 19 and the tial that the axis of the rock shaft 13 be at a right angle to the punch slide 19. If such 'was not the case the punch slide did not operate efficiently, frequently binding in its ways, causing unusual and unecessary wear on the parts, the fastening means therebetween frequently became broken by reason of the undue and unequal strains: upon some of the parts and in other ways the improper alignment of the parts produced conditions that were grossly unsatisfactory.

fMachining of the parts to secure this right angle relation', increased with the size of the header, thus adding materially to the cost of the machine. Also if the right angle re lation was not obtained, the bigger and more powerful the header the greater such objections became.

iii)

With my improvement, it is absolutely immaterial so far as the punch slide 19 is concerned whether the axis of the shaft 13 is in right angle thereto or not as the hinged connection between it and the. shifter slide accommodates any inaccuracy.

In Figures Sand 4: I have illustrated an alternative form of the cradle 18, having a single gib 23 therein instead of two as illustrated in Figures 1 and 2. The single is held against cndwise movement by the pin 29, rather than by the overhanging lips at each end as in the form shown in Figures 1 :and 2. Obviously these forms of 'gibs may be used interchangeably if desired.

Minor changes! and alterations may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit my self to theexact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.

What I claim as new and by Letters Patent, is:

1. In a device of the character described, a gate; a punch slide on said gate; a shifter plate; a pivotal connection between said shifter plate and punch slide; and means for imparting movement to said shifter plate desire to secure whereby said punch slide may be movedupon said gate in a path at an angle to that of said gate.

2. In a device of the character described, a body member; a shaft journaled therein; a gate movably mounted in said body; a punch slide on said gate; and flexible means between said shaft and punch slide for imparting movement to said punch slide upon saic gate irrespective ofthe angle-between the axis of said shaft and said punch slide.

3. A device of the character described having a gate, a punch slide movably mounted therein, a rock shaft, and means for imparting movement to said punch slide from said rock shaft comprising mechanism havmg a sliding and pivotal connection with said shaft.

i. A device of the character described having a gate, a punch slide movably mount- I ed therein, a rock member, a shifter plate movably mounted therein, interlocking lugs upon said punch slide and shifter plate, and a pin connecting said lugs.

In a device of the character described. having a gate; a punch. slide movably mounted thereon; a rock member; and a shifter plate movably connected with said rock member and in part moved thereby, having a hinged connection with said slide.

shifter plate'movable with said slide and having a hinged connection therewith, the axis of said hinged connection being sub stantially parallel with the direction of movement of said gate;

8. In combination with the gate of adevice of the character described; a punch slide movably mounted thereon; a shifter plate movable with-said slide and meansrfor connecting said shifter platewith said punch slide whereby the same may rock in one direction relatively thereto and beheld against movement in the opposite direction,

said means comprising a hinge member connecting interlocking parts upon the slide and shifter plate.

9. In a device of the character described, a reciprocating gate; a punch slide movably mounted thereon; a rock shaft; a connection between said rock shaft and slidewhereby.

the movement of said rock shaft imparts amovement to said punch slide upon said gate during the reciprocation thereof, said means comprising in part a member having an operative connection with said rock shaft and a hinged connection with said punch slide,

said member moving as a unit with said punch slide.

10.,In a device of the character described, having a gate; a punch slide movably mounted thereon; a rock member; and a shifter plate movably connected with said rock member and operated thereby, having a hinged connection with said slide, the axis of said member and that of said hinged connection being at substantially a right angle to each other. r p

11. In a device of the character described, a body member; a gate slidably mounted thereon; a shaft below said gate, the axis of which is at substantiallya right angle to the direction of movement of said gate a punch slide movable upon said gate; and means between said shaft and said punch slide for imparting movement-from' said shaft to said punch slide uponsaid gate, said meanscomprising in part a hinge member, the axis of which is at substantially a right angle to the axis of said shaft.

In testimony whereof, I have hereunto v affixed my signature.

RICHARD LESTER wrncox.
